ذَلِكَ بِأَنَّهُمْ كَرِهُوا مَا أَنزَلَ اللَّهُ فَأَحْبَطَ أَعْمَالَهُمْ
[47:9]
That is because they hated what Allah revealed, so He rendered their deeds null.
That is because they hate the Revelation of Allah; so He has made their deeds fruitless.
That is because they are averse to that which Allah hath revealed, therefor maketh He their actions fruitless.
